Cañada Del Oro
The Cañada del Oro (Spanish for ''Canyon of Gold''), is a primary watershed channel in the valley of Oro Valley, Arizona, US. The word ''cañada'' has a tilde ''( ñ)'' and is pronounced in Spanish; in English it is pronounced , not like the country of Canada. The Cañada del Oro originates in the remote Canyon del Oro in the Santa Catalina Mountains north of Tucson, fed by rainfall and melted snow from the northern face of Mount Lemmon and flows northward toward the town of Oracle. The Cañada del Oro is a perennial creek in Canyon del Oro while at higher altitudes. The Cañada del Oro curves from flowing northward to southward through the town of Oro Valley north of Tucson, where it is usually a dry riverbed. In Oro Valley the Cañada del Oro collects watershed from the western face of the Santa Catalina Mountains. The Cañada del Oro ultimately feeds into the Santa Cruz River just northwest of Tucson, the principal watershed channel in the Tucson valley. Historically, ...

Mount Lemmon
Mount Lemmon, with a summit elevation of , is the highest point in the Santa Catalina Mountains. It is located in the Coronado National Forest north of Tucson, Arizona, United States. Mount Lemmon was named for botanist Sara Plummer Lemmon, who trekked to the top of the mountain with her husband and E. O. Stratton, a local rancher, by horse and foot in 1881. Mount Lemmon is also known as Babad Do'ag, or Frog Mountain to the Tohono O'odham. Geography Climate Due to the elevation change from the bottom to the top, the summit of the mountain can be twenty to thirty degrees cooler than the base. It usually sees at least one snow fall during the winter months, making it a cool escape and popular tourist attraction for Tucson inhabitants. Geology Mount Lemmon is made up of Bolsa Quartzite, Dripping Spring Quartzite, and a local sandstone and conglomerate. The portions have been intruded by a Diabase Dike of the Apace Group. Summerhaven Summerhaven is a small town near the to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altitudes
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or ...

Canyons And Gorges Of Arizona
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Tucson, Arizona
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harold Bell Wright
Harold Bell Wright (May 4, 1872 – May 24, 1944) was a best-selling American writer of fiction, essays, and nonfiction. Although mostly forgotten or ignored after the middle of the 20th century, he had a very successful career; he is said to have been the first American writer to sell a million copies of a novel and the first to make $1 million from writing fiction. Between 1902 and 1942 Wright wrote 19 books, several stage plays, and many magazine articles. More than 15 movies were made or claimed to be made from Wright's stories, including Gary Cooper's first major movie, ''The Winning of Barbara Worth'' (1926) and the John Wayne film '' The Shepherd of the Hills'' (1941). Early life Wright was born in Rome, New York, to Alma Watson and William A. Wright. In his autobiography, ''To My Sons'', Wright reports that his father, a former Civil War lieutenant and lifetime alcoholic, dragged "his wife and children from place to place, existing from hand to mouth, sinking deeper and de ...

Lost Mines
Lost mines are a popular form of lost treasure legend. The mines involved usually contain a high-value commodity such as gold, silver or diamonds. Often, there is a map (sometimes called a "waybill") purportedly showing the location of the mine. Common reasons for the mines being lost include: * The mine was discovered and worked by a recluse who refuses to divulge the location, and dies without revealing the location. * The mine was worked by native peoples who refuse to divulge the location to others. * The mineral deposit was discovered in a remote location, and upon returning to the area the discoverer could not find it again. * The discoverer died of hunger, thirst, or exposure shortly after discovering the deposit, and his body is found with rich ore specimens in his possession. * The discoverers were killed by hostile natives. Sometimes the natives cover up the entrance to the mine. * In Spanish Empire colonies in the New World, many lost mines were supposedly worked u ...

Placer Mining
Placer mining () is the mining of stream bed ( alluvial) deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup in Canada.

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct ...

Mexican–American War
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the (''United States intervention in Mexico''), was an armed conflict between the United States and Mexico from 1846 to 1848. It followed the 1845 American annexation of Texas, which Mexico still considered its territory. Mexico refused to recognize the Velasco treaty, because it was signed by President Antonio López de Santa Anna while he was captured by the Texan Army during the 1836 Texas Revolution. The Republic of Texas was ''de facto'' an independent country, but most of its Anglo-American citizens wanted to be annexed by the United States. Sectional politics over slavery in the United States were preventing annexation because Texas would have been admitted as a slave state, upsetting the balance of power between Northern free states and Southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of expand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
